Automatically remove Subversion unversioned files

Question

Does anybody know a way to recursively remove all files in a working copy that are not under version control? (I need this to get more reliable results in my automatic build

My C# conversion of Thomas Watnedals Python script:

Console.WriteLine("SVN cleaning directory {0}", directory);

Directory.SetCurrentDirectory(directory);

var psi = new ProcessStartInfo("svn.exe", "status --non-interactive");
psi.UseShellExecute = false;
psi.RedirectStandardOutput = true;
psi.WorkingDirectory = directory;

using (var process = Process.Start(psi))
{
    string line = process.StandardOutput.ReadLine();
    while (line != null)
    {
        if (line.Length > 7)
        {
            if (line[0] == '?')
            {
                string relativePath = line.Substring(7);
                Console.WriteLine(relativePath);

                string path = Path.Combine(directory, relativePath);
                if (Directory.Exists(path))
                {
                    Directory.Delete(path, true);
                }
                else if (File.Exists(path))
                {
                    File.Delete(path);
                }
            }
        }
        line = process.StandardOutput.ReadLine();
    }
}
